Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
A vulnerability has been identified in Tecnomatix Plant Simulation V2201 (All versions < V2201.0008), Tecnomatix Plant Simulation V2302 (All versions < V2302.0002). The affected application is vulnerable to stack-based buffer overflow while parsing specially crafted STP files. This could allow an attacker to execute code in the context of the current process. (ZDI-CAN-21054)

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

Tecnomatix Plant Simulation contains a stack-based buffer overflow vulnerability when parsing specially crafted STP files. An attacker can exploit this by convincing a user to open a malicious STP file, potentially allowing arbitrary code execution in the context of the current process. The vulnerability affects V2201 versions before V2201.0008 and V2302 versions before V2302.0002.

MitigationApply the vendor patches (V2201.0008 or V2302.0002) to resolve the vulnerability. Additionally, enforce strict validation of STP files from untrusted sources and consider restricting file handling privileges of the affected application.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Verify Tecnomatix Plant Simulation installation
    Check for the presence of the Tecnomatix Plant Simulation application in the system. Common installation paths include C:\Program Files\Siemens\Tecnomatix_Plant_Simulation or C:\Program Files (x86)\Siemens\Tecnomatix_Plant_Simulation. Use PowerShell Get-ItemProperty or check the Windows registry under HKLM:\SOFTWARE\Siemens\Tecnomatix to confirm installation.
    Affected if The application is not installed on the system.
  2. Identify installed version number
    Locate the version information for Tecnomatix Plant Simulation. Check the application's About dialog, the file properties of the main executable (typically PlantSimulation.exe), or query the Windows registry under the Tecnomatix installation key for the Version or ProductVersion value.
    Affected if Unable to determine the installed version.
  3. Compare version against affected ranges
    Evaluate whether the installed version falls within V2201 versions before V2201.0008 OR V2302 versions before V2302.0002. The vulnerable versions are: 2201.0000 through 2201.0007, and 2302.0000 through 2302.0001.
    Affected if The installed version is 2201.0000-2201.0007 or 2302.0000-2302.0001.
  4. Confirm STP file handling capability
    Verify that the Plant Simulation environment can import or open STP (STEP) files. This is typically enabled through the CAD import functionality or the Plant Simulation CAD interface module. Check if the application has CAD conversion or import features loaded.
    Affected if STP file handling is available and the user can open or import STP files within the application.

The environment is affected if Tecnomatix Plant Simulation is installed with a version between 2201.0000-2201.0007 or 2302.0000-2302.0001 and has the capability to open or import STP files.

Upgrade available Upgrade to 2201.0008 / 2302.0002 or later
Fixed in 2201.00082302.0002
Interim mitigation

Apply the vendor patches (V2201.0008 or V2302.0002) to resolve the vulnerability. Additionally, enforce strict validation of STP files from untrusted sources and consider restricting file handling privileges of the affected application.

Recommended fix High confidence

Tecnomatix Plant Simulation V2201.0008 or V2302.0002 (depending on your current branch)

  1. 1. Identify the currently installed version of Tecnomatix Plant Simulation (help > about or similar)
  2. 2. If running V2201.x, upgrade to version 2201.0008
  3. 3. If running V2302.x, upgrade to version 2302.0002
  4. 4. Obtain the update from the Siemens support portal (cert-portal.siemens.com or siemens.com/support)
  5. 5. Back up any critical Plant Simulation models and projects before applying the update
  6. 6. Install the update following standard Siemens installation procedures
  7. 7. Verify the installation was successful by checking the version number (help > about)
Caveat Review Siemens release notes for your version; minor version updates typically have low risk but validate critical models in a test environment first
